In my experience, I read first part of ISO-7816-4.
APDU(CLA, INS, P1P2 and so on), logical channel and secure message.
And I read GP Card Spec v2.1.1.
It include some examples and basic commands.
Don't peruse ISO spec first. That is difficult and abstract for beginner I think.
iso 7816 and 14443 are not about payment. for payment, see EMV and EMVco specs.
however they are a good reference for generic card commands.
